' Application filed March 22, 1902. 3erial No 99.493. (N morleLl To all whom it mag concern.-

Be it known that we, FERDINAND CHARRON and Leonor: GIRABDOT, citizens of the Republic of France, residing at No. 45 Avenue de la Grande Arme, Paris, in the Republic of France,have invented certain new and useful Improvements in the Construction of Charge-Inlet Devices for Explosive-Engines, of which the followingis a specification.

Our invention relates to improvements in means for conducting combustible fluid to the suction-valves in petrol or gas motors in order to allow of rapid access to the said valves by a simple method of mounting and dismountin g. ticularly gas-motors, give only a comparatively small amountof power from each cylinder,said motors are generally built with two A considerable amount of time and work is then required in order to obtain access to the valves of the va rious cylinders, since it is necessary for that purpose to disconnect a'large number of parts.

With our invention it is su fficient for each pair of cylinders to slightly loosen a screw and then move one part on its pivot. The operation is therefore practically an instanta- IlGOllS one.

The annexed drawings illustrate our invention applied to a four-cylinder motor.

Figure 1 is a sectional elevation of the feedpipes, showing the parts for two supply-valves i of which terminates in a cap d, belonging to one of the suction-valves. The caps cl bear on the seats g of the valves f and are held in position in pairs by means of cross-heads h, pivoted on standards 0, fixed to the motorcylinder frame. Nuts j, which are screwed onto the screw threaded ends of the standards 0, press against the cross-heads h. This simple fastening of each nut j presses two Since explosion-motors, and more par-' caps d against the respective seats g and presses the latter against the joints It, thus insuring a tight fit to prevent the escape of gas when the explosion takes place.

In order to obtain access to the valves of two adjacent cylinders, it is sufficient to slightly loosen the respective nut j and to swing the cross-head it into a position perpendicular to that which it previously occupied in its working position and to raise the pipe (3 into the position shown in Fig. 3, causing it to rotate on the joint I). The reverse operation places the mechanism in its working positionagain.

It will be seen that the operation is simple and speedy and very serviceable, more particularly for automobile-motors.

In the drawings the arrangement is com- ,pleted by the throttle p for regulating the section of passage for the combustible fluid passing to the motor.

This construction may be applied in an analogous manner to internalcombustion motors of all systems with any number of cylinders.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, isa v 1. An improved device for supply of combustible fluid in explosive-motors, comprising a gas-supply pipe at fixed in position and terminating in a joint I), in combination with a pipe 0 pivoted at one end in the said joint I) and terminating at the other end in a cap d which bears on the seat 9 of the suctionvalve f, a cross-head h revoluble on a standard 0 and bearing on the cap (1, and. a nut j which screws onto the screw-threaded end of the standard 0 and is adapted to press against the cross-head or to leave the latter free, substantially as and for the purpose set forth.

2. An improved device for supplying combustible fluid in two-cylinder explosive-motors comprising a gas-supply pipe a fixed in position and terminating in a joint I), in combination with a pipe 0 pivoted at one end in the joint I) and dividing at the other end into two branches each of which terminates in a cap d, which bears on the seat 9 of the respective suction-valve f, a cross-head with two arms h which is rotatable on a standard 0 between the two admission-ports, each of the said arms bearing on one of the caps d, and a nutj adapted to screw onto the screwthreaded end of the standard 0 and to press onto the cross-head or to leave the latter free to revolve, substantially as and for the purpose admission-ports of two adjacent cylinders, each of the said cross-heads being adapted to simultaneously bear on two of the caps d, and nutsj each of which is adapted to screw onto the screw-threaded end of one of the standards 0 and to allow of pressure being brought to bear on the respective cross-head h or of loosening the said cross-head, substantially as and for the purpose set forth.

In.witness whereof We have hereunto set our hands in presence of two witnesses.
